    According to bond order concept, the correct order of stability of\[{{\text{O}}_{\text{2}}}\text{,O}_{\text{2}}^{\text{+}}\] and \[\text{O}_{2}^{-}\] is

    A) \[{{O}_{2}}>O_{2}^{+}>O_{2}^{-}\]

    B) \[O_{2}^{-}>{{O}_{2}}>O_{2}^{+}\]

    C)  \[{{O}_{2}}>O_{2}^{-}>O_{2}^{+}\]

    D)  \[O_{2}^{+}>{{O}_{2}}<O_{2}^{-}\]

    Correct Answer: D

    Solution :

     Bond order \[\propto \]stability Species          Bond order \[O_{2}^{+}\]                   \[2.5\] \[{{O}_{2}}\]                    \[2.0\] \[O_{2}^{-}\]                    \[1.5\] Hence, the order of stability is
